Description

Technical Field

[0001] The utility model belongs to the technical field of air treatment, and in particular relates to a bag-type filter partition structure. Background Art

[0002] In the rotary dehumidifier unit, air dehumidifier unit, air handling unit, dehumidification air conditioning unit, constant temperature and humidity unit, the bag filter is one of the important components of the unit; the commonly used installation structure is to make an installation frame corresponding to the size of the bag filter frame, and then fix the installation frame in the corresponding bag filter functional section partition of the unit, and the bag filter functional section partition is fixed inside the chassis of the unit; the bag filter installation frame will be made into standard size frames according to some standard bag filter size specifications as inventory, and the bag filter installation frame of the corresponding size specifications will be used according to the production needs of the unit.

[0003] During the manufacturing process of some non-standard units, if the standard bag filter cannot meet the performance requirements of the unit, the bag filter needs to be resized. In this case, the standard bag filter mounting frame cannot meet the requirements. At this time, the bag filter mounting frame needs to be remade, which prolongs the manufacturing time. The cost of manufacturing the standard bag filter mounting frame is relatively high. Due to the overlapping use of some sheet metal materials, the bag filter mounting frame needs to be reinstalled in the bag filter functional section partition. The installation time here is also repeated, so this structure is also one of the reasons for the high cost.

[0004] The standard bag filter installation frame must have some unmanageable connection gaps during installation. These connection gaps will cause the filter function section to lose bag filter efficiency.

[0005] Chinese patent publication number CN206037373U discloses a quick-installation structure for primary and secondary efficiency filters. The filter frame is welded integrally to form a grid of independent units. The filter frame is provided with a press groove with screw holes. Locking nuts, press blocks, and bolts fit within the screw holes. The press groove is welded to the unit frame as a single unit, and sealing strips are affixed to the inner four sides of the press groove. The filter frame is formed from steel plate through sheet metal processing and welded integrally into a grid unit. It is supplemented with elastic sealing strips, butterfly locking bolts, and single and double press blocks. This prevents dust leakage through gaps in the assembled unitized mounting frame. The integral weld provides excellent strength and prevents deformation, improving the air quality of the air conditioning unit.

[0006] In the above-mentioned patent solution, although the sealing strip can block the gap, if the filter and the sealing strip are not pressed tightly together, the gap will still exist and the sealing effect will not be sufficient. Therefore, it is necessary to press the filter and the sealing strip together with one hand, and then use the other hand to rotate the locking bolt to fix it. However, since the front of the bag filter is opened with ventilation holes to increase the ventilation area, its strength is not high, and the rigid outer frame of the bag filter is often narrow, so it is inconvenient to press the filter. At the same time, the installation location of the rotary dehumidifier does not always have a large enough operating space to allow two hands to operate at the same time, which also causes inconvenience in operation.
